The Meatest M191 Insulation Tester Calibrator is designed for the calibration of insulation testers. It can be used for calibration of any DC high resistance meter with working voltage up to 10 kV.

Meatest M191 Insulation Tester Calibrator is based on programmable high resistance decade which is completed with additional electronic circuits allowing calibration not only resistance ranges, but also calibration of test voltage generated by UUT, testing of short current, verifying of functions of measuring dielectric parameters like polarization index (PI), dielectric absorption ratio (DAR) and polarization ratio (PR). The calibrator enables also verification of timer function of UUTs.

Basic feature of the Meatest M191 Insulation Tester Calibrator is adjustable high resistance decades in the range from 10 kΩ to 1 TΩ. The decade is designed for operation voltages up to 10 kV. In this range it offers basic accuracy 0.1% to 5 % depending on set resistance value.

The calibration can be controlled manually using front panel keypad or in remote mode using one of two types of interfaces GPIB, or RS-232.

The Meatest M191 Insulation Tester Calibrator can easily integrate within calibration systems featuring CALIBER software support.
